LLOYD NOTTINGHAM, OF NORFOLK, VIRGINIA.

GRAiN-REGiSTER.

EEPECIFECATION forming part of Letters Patent No. 337,859, dated March 16, 1886.

Serial No. 105,537.

(No model.)

To all whom it may concern.-

Be it known that I, LLOYD NOTTINGHAM, a citizen of the United States, residingat Norfolk,in the county ofNorfolk and State ofVirginia, have invented a new and useful Improvement in Tally-Counters, of which the following is a description.

This invention relates to that class of devices which are used for keeping tally in counting measures of grain, and for any othertallykeeping to relieve the memory ofthe operator; and the object of the invention is to provide a simple and inexpensive device which shall indicate on a dial the number of counts it has received at any time.

To this end my invent-ion consists in the construction and combination of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure l is a front elevation of my invention. Fig. 2 is a front elevation of the same with the cap, hands, and dial removed; and Fig. 3 is a vertical section of the same.

A represents the body of the machine, and B a glass cover or crystal therefor secured in a ring, which screws into the ease to attach the crystal thereto.

O is a dial graduated into equal divisions numbered to one hundred, and attached to the body A in any usual manner, such as by the steady-pin M.

D is a ratchet-wheel having one hundred teeth to be engaged by a pawl, E, and pivoted to revolve 011 a stud, P, which is fixed centrally in the body A. The pawl E is pivoted at its rear end to a spring, K, which is operated by aradial push-pin, G, and stands as a brace somewhat tangent to the wheel D, so that by pushing the pin G toward center the pawl advances circumferentially, carrying the wheel along with it. The amount of this advance is regulated to correspond to the movement of the wheel D, one tooth by the knob H being fixed on the push-pin G, so as to strike upon the body A when the pin has been pushed in the required distance.

J is a spring secured to thepawl and sliding within the rim of the body A, and acting to engage the pawl with the ratchet wheel. The

springKis secured at one end to the body, and bears at its other end on the inner end of the push-pin, to crowd it outward, thereby returning both the push-pin and the pawl to their normal positions after each advance made by them.

The wheel D is provided witha quill, L, extending out through the dial, and the outside or long hand, N, is removably secured there' on. Thus every push of the knob H is registered by turning the wheel D one tooth and turning the hand N one unit on the dial.

O is a spring pawl or detent to keep the wheel D as set by each push of the pawl E.

P is another ratchet-wheel having one hund red teeth, and mounted to revolve with a close frictional tit within the dial O and a free lit around the quill L. The frictional fit prevents this wheel P from revolving either for ward or backward until it is moved by the pawl Q. This is a mate to the pawlE, is hung to the spring K, and is operated atevery move thereof; but it is prevented from engaging with the wheel 1? by a projecting rim, it, of the wheel D,which rim surrou n dsthe said wheel P.

S is anotch in the rim it in the path of the pawl Q, and when ninety-nine teeth of the wheel D have been moved forward this notch permits the pawl Q to fall through the notch into engagement with the wheel P. The next move of the push-pin brings up the one-hundredth tooth of wheel D, and at the same time moves wheel P forward one tooth. The next move of the push-pin brings the rim It under the pawl Q, which rides thereon until the notch is brought around by the second hundred pushes of the pushpin. Then it moves the wheel]? the second notch. These movements of wheel P are registered on the dial by the short hand T, which is removably fixed upon a short quill, a, of the wheel 1?. By this means a single dial graduated to one hundred registers movements of the puslrpin up to one hundred times one hundred, or ten thousand. This pawl, pushpin, and ratchet-wheel arrangement would serve up to one hundred by numbering the face of the wheel D as a dial. The same effect would be produced if the pawls were pivoted directly to the inner end of the push-pin.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The combination of the body or case, a wheel j ournaled thereto and having a lateral annular flange provided with a notch or gap, a second wheel journaled within the annular IOC flange, a pair of pawls arranged laterally to and two pawls pivoted to said support and loeach other, one of said pawls being arranged cated laterally one to the other, one of said to engage the first wheel and the other to rest pawls being arranged to engage the first wheel I 5 on theannular flange and to project atintervals and the other the second wheel at intervals 5 through the gap thereof and engage the second through the gap of the annular flange, said wheel, and a pin or stem connected with said pawls being supported independently of the pawls, whereby they may be actuated, substan- I wheels, substantially as set forth. tially as set forth.
